High-grade test blocks and calibration foils are preconditions for easy check and reliable calibration of coating thickness gauges. Depending on the application and measuring range, ferromagnetic (FE) and nonferromagnetic (NFE) test blocks of different sizes as well as a large selection of suitable calibrating sets of foils exactly defined and with stated thickness recorded on the foil are available. If you need to meet higher demands: Our calibrating sets of foils available with the denotation "precision" come with even further reduced thickness tolerances. Upon request, calibrating foils with individual Quality Certificate are supplied.
